In building and automation technology switching signals are generated at various locations but are needed then at a central location.

In such cases the digital Web-IOs make it possible to configure switching actions that cause an input change at Position A to switch an output at Position B.

Whereas in the Box-to-Box approach there is a rigid 1:1 association of the outputs to the inputs, actions allow inputs and outputs even on different Web-IOs to be associated as desired. At least one action must be configured for each of these point-to-point connections.

How it’s done

• Provide power to the Web-IO and connect the IOs
• Simply connect two Web-IO boxes to the network at the corresponding locations
• Assign IP addresses
• For the Web-IO on which an input is switched, one action for a change to ON and another for a change to OFF, in which you specify which output should switch which Web-IOs
• For the Web-IO on which an output is to be switched, the Web-APU must be enabled and the corresponding output enabled for switching.

As soon as these steps are completed, the output on the one Web-IO follows the input of the other.
